All ioctl commands for sd card go to timeout

[davideferraretto]

WIth sdtools or mmc all cmd go to timeout.
For example if i try
sudo ./mmc status get /dev/mmcblk0
then i'll get
ioctl: Connection timed out
Could not read response to SEND_STATUS from /dev/mmcblk0

I have a Pi3B+ with debian 10 (buster)
kernel: Linux raspberrypi 5.4.51-v7+ #1333 SMP Mon Aug 10 16:45:19 BST 2020 armv7l GNU/Linux
With dmesg I see
[ 941.588296] mmcblk0:
[ 1783.869652] sdhost-bcm2835 3f202000.mmc: __mmc_blk_ioctl_cmd: cmd error -110

Thanks.

From the comments on the issue on the sdtool maintainer's site (BertoldVdb/sdtool#10), it isn't understood and also doesn't appear to be specific to Raspberry Pi.

I believe these are different issues. The sdtool problem was introduced in 5.5 and fixed in 5.10 (BertoldVdb/sdtool#10). But the mmc tool fails for all kernels that I've tested 4.18 to 5.11.

And the mmc tool fails fast, whereas sdtool spins for a couple of seconds before timing out.

sdtool works for me, example:

dave@sys:~$ sudo ./amd64-sdtool /dev/mmcblk0 status
[+] Found RCA for /dev/mmcblk0: XXXX.
[+] Card CSD: 4XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX.
[+] Write protection state: Off.

While mmc always fails:

dave@sys:~$ sudo mmc extcsd read  /dev/mmcblk0
ioctl: Connection timed out
Could not read EXT_CSD from /dev/mmcblk0
